Hello, I have repaired on top of 30000 vehicles in my career and I obsession to ask you questions back I am not there in person to gather together facts, data, or to exam your vehicle. I may question you to statute scrutiny in my stead. If breakdown is needed and you would rather not feint testing, I can have enough money my best advice, Fuel pressure?
I started the car going on this morning, it starts going on and runs at 1750 and within a minute or therefore climbs on top of 2500.. It is doling out mild though, just pretension later than it should be. I plus checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it help to exactly where it was. No vacuum leak sounds and every friends verified. I vibes good about them as I've been in there a bunch of times..
next I begin the car, the engine surges going on amid 1200 and 2000 rpm put up to and forth. I misused the IAC and the TPS considering no change in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to accustom yourself the idle speed screw to lower the rpm and it would keep for a while. Now, the engine is continuously surging to the reduction where I cannot drive it for agitation of damage to the steer train. Any experienced solution?
